SAUSAGE-STUFFING- MACHINE.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed August 28,1905. Serial No. 275,983-

and useful Improvements in Sausage-Stuffing Machines, of which thefollowing is a specification.

My invention relates to improvements in sausage stuffing machines, andhas for its objects to provide a machine of the kind stated Whichissimple in construction, el'licient in operation and easy tomanipulate.

With a view to attaining these and other objects which will becomeapparent to those skilled in the art from the following description myinvention consists in the features hereinafter set forth and specifiedin the claims.

In the drawings: Figure 1 is a side elevation of the complete machine.Fig. 2 is a central section through the upper part thereof. Fig. 3 is asection on line 33 of Fig. 2. Fig. 4 is a fragmentary section on line 4%of Fig. 2.

Throughout the drawings like numerals of reference refer always to likeparts.

In the drawings 5 indicates a suitable frame or bed wherein is mounted asecondary frame 6, comprising metallicside pieces 7-7.

the secondary frame 6, prcferablyin inclined position,

its lower end resting upon a rod 11 traversing the secondary frame andits upper end being sustained and positioned by the engagement ofnotches 12 in a rim or flange 8 of the cylinder with studs 13 carried bythe side pieces 7 of the secondary frame. Arranged for co-action withthe cylinder is a reciprocable piston or plunger 14 carried by arack-bar 15, toothed as at 16 preferably on its under side, forengagement with a driving gear 17, whose shaft 18 is journaled in theframe pieces 77 and preferably projects beyond one of said side pieces.

19 indicates suitable guides for the rack-bar 15.

20 indicates a ratchet wheel secured to the shaft 18, and 21 indicatesthe dog therefor pivoted as at 22 to an oscillating arm 23 pivoting onthe shaft 18 and at its outer end connected by a link 24 to a pivotedtreadle 25, normally maintained in raised position by a spring 26. Itwill be apparent now that as the lever 25 is depressed and the arm 23drawn downward, the pawl 22 engages with ratchet 20 and advances thesame,

so rotating the gear wheel 17 to feed forward the rackbar 15.

The rack-bar 15 is preferably made automatically returnable torear-1nost position and means are pro- 5 vided for normally preventingits return. To these ends I provide a weight 27, connected with therackbar 15 by a cord 28 running over a pulley 29, as a means forautomatically returning the rack-bar, and I provide .also a dog coactingwith a suitable moving part of the mechanism for normally preventing thereturn of the rack-bar under the influence of its weight 27.Specifically 30 indicates a saw-toothed rack provided on the upper faceof the bar 15, and 31 indicates a gravity pawl carried by a guide 19 andnormally engaging the rack 30 to permit its forward movement but toprevent its return.

In general the operation of my machine is as follows:

The rack-bar being in rear-most position, a cylinder 8,

filled with sausage meat or the like is placed in position in the frameand the end of a sausage casing slipped over the nipple 10. Now the footlever or treadle 25 is operated to dog the ratchet 20 around, sorotating the gear 17 and advancing the rack-bar 15 so that the piston 14presses the meat out at the nipple 10 into the sausage casing. Aftersuch operation the dogs 31 and 21 are lifted from engagement with rack30 and ratchet 20 and the rack-bar, freed from restraint, automaticallyreturns to rear-most position under the influence of its weight 27 Nowthe empty cylinder 8 may readily be removed and a full cylindersubstituted therefor.

From the foregoing it will be seen that the support consists of the mainframe 5, which may be an ordinary wooden or other suitable frame, andthe secondary frame comprising two integral metallic side members 6,joined at one end by the transverse bar or support 11, the transverseshaft 18 being journaled at the opposite end of said side pieces, fromwhich shaft the piston 14- is operated. It will also be observed thatthe cylinder 8 is supported by the pins 13 carried by the side members6. By this arrangement the strain of the work is thrown upon themetallic side members of the secondary frame, and the main frame,therefore, has but the additional function of furnishing bearings forthe Weight 27 and the operating treadle 25.

While I have herein described specifically an embodiment of myinvention, which I have found to be practical, it will be apparent thatchanges might be made therein without departure from the spirit or scopeof my invention.

What I claim as new and desire to secure by Letters.

Patent of the United States is:

1. In a machine of the class described, the combination with a mainframe, of a secondary frame mounted thereon and adapted to take thestrain of the work, said secondary frame including integral metallicside members, a transverse support connecting said side members at oneof their ends, a shaft journaled in said side members at the other end,inwardly-extending pins carried by said side members intermediate thetransverse support and said shaft, a cylinder arranged in said secondaryframe and resting upon the transverse support of the latter, saidcylinder provided with an encircling rim having notches in its sides forreceiving the inwardlycxtending pins of the secondary frame whereby thecylinder is detachably held in said secondary frame, a piston arrangedfor insertion in said cylinder, a rack bar for operating said piston, agear wheel carried by the shaft of the secondary frame and coacting withsaid rack bar for moving the piston in one direction in the cylinder,means for moving the piston in the opposite direction, and means carriedby the main frame and connected to the shaft of the secondary frame foractuating said shaft.

2. In a machine of the class described, the combination with a mainframe, of a secondary frame mounted thereon and adapted to take thestrain of the work, said secondary frame including integral metallicside members, a transverse support connecting said side members at oneof their ends, a shaft journaled in said side members at the other end,inwardly extending pins carried by said side members intermediate the'transverse support and said shaft, a cylinder arranged in said secondaryframe and resting upon the transverse support of the latter, saidcylinder provided with an encircling rim having notches in its sides forreceiving the inwardly extending pins of the secondary frame, wherebythe cylinder is detachably held in said secondary frame, a pistonarranged for insertion in said cylinder, a rack bar for operating saidpiston, a gear wheel carried by the shaft of the secondary frame andcoacting with said rack 'bar for moving the piston in one direction inthe cylinder, a weight supported by the main frame "and suitablyconnected to said piston for moving the latter in the oppositedirection, and means also carried by the main frame and connected to theshaft of the secondary frame for actuating said shaft.

' In testimony whereof I hereunto set my hand in the presence of twowitnesses.
